hello, I am still a PPC G5 user but not for long as i bought a macpro 1.1 (2.1) model, used, recently. I have a cinema 21" display and use D65, 1.8 gamma for ages. I mainly set this gamma for prepress applications and worked ok insofar. I do though change my workflow, adding more video to my stock collections, which need sRgb space for beter colour space match etc. not sure if 1.8 is adequate for video.... I recently read that the macpro devices have different Gamma by default if i am not mistaken, 2.2 and many monitors working with photoshop and web i presume are on sRGB@2.2 gamma. I am a bit confused by this and would like to ask your opinions on how you are affected or using the gamma and calibrate the monitors ? Do you use the 2.2 and why ? Do you also use this gamma for prepress ? I will be moving to the macpro soon and i am not sure if is better to copy my ICC profile from the G5 to the macpro and continue my work as with the G5.
